  • Patent number: 11005301
    Abstract: Systems and methods for ensuring that resonant inductive power transfer goes only to authorized users using encryption. Resonant inductive power transfer requires near-identical resonant frequencies in the transmitter and the receiver. The frequency of the power transfer signal changes on a schedule known only to the transmitter and receiver so a “power eavesdropper” cannot track the frequency well enough to efficiently receive power. To make the frequency transitions energetically efficient, a capacitive or inductive element is switched in or out of each circuit at moments of zero-crossing: zero charge on a capacitor or zero current in an inductor. To maintain phase alignment, either switching an inductor on the transmit side is nearly simultaneous with switching a capacitor on the receive side, or switching a capacitor on the transmit side is nearly simultaneous with switching an inductor on the receive side.

  • Patent number: 10992292
    Abstract: Methods, systems, and computer readable media described herein can be operable to facilitate transitioning a device from a first state to a second state. A switch described herein allows for the use of an electronic circuit to perform the toggle and persistence functions while simultaneously giving more flexibility to the industrial design and physical switch implementation. The switch allows this preserving of the state using only a toggle on a voltage and thus allowing for a hardware only solution. The switch described herein allows for the use of smaller and less complicated mechanical switches allowing for more compact industrial designs. The switch uses a programmable voltage reference as a 1 bit non-volatile memory cell that is programmed by means of a logic pulse to the device. This allows a software independent setting of the state of the privacy switch. This state will remain through power cycles.

  • Patent number: 10985748
    Abstract: This disclosure describes a gate driver with voltage boosting capabilities. In some embodiments, the gate driver may comprise a charge pump that includes capacitor(s) and switch(es). Responsive a logic low input signal, the gate driver may bypass the capacitor(s) to allow the input digital signal to drive the gating signal directly. Conversely, responsive to a logic high input signal, the gate driver may couple the capacitor(s) in series with the input digital signal to generate a boosted gating signal. In some embodiments, the gate driver may comprise an inductor-capacitor resonant circuit to create a doubled output gating signal with respect to the input digital signal. In some embodiments, the resonant gate driver may include an additional voltage boosting capability that can be selectively enabled to compensate for a voltage drop during the signal transfer from the input to the output.
